In the Safari browser, posted photos appear to the right side of the message "box" rather than under the message at the left margin. Is it supposed to be this way? It appears that older posts' photos still display on the left.

Jim, I am experiencing the same, pictures displaced to the right, only on my MAC. This seems to be only occurring in the production variants portion. I did post a reply in the prewar section and the picture was positioned correctly. You are not limited to Safari on a MAC.
